Abstract

A conveyance apparatus for conveying a mold into an injection molding machine includes a frame configured to form a supporting plane for supporting the mold, and an actuator configured to move the mold along the supporting plane between a first position inside the injection molding machine and a second position different from the first position, wherein the improvement to the conveyance apparatus includes the actuator being located below the supporting plane in a vertical direction; and a linking unit configured to link the mold and the actuator, wherein the linking unit is connectable to a side surface of the mold, wherein, in a state where the mold is at the second position, at least a part of the actuator is closer to the injection molding machine than the side surface of the mold in a conveying direction where the actuator moves the mold.

Claims (63)

1. A conveyance apparatus for conveying a mold into an injection molding machine, the conveyance apparatus comprising:

a frame forming a supporting plane for supporting the mold;

an actuator configured to move the mold along the supporting plane between a first position inside the injection molding machine and a second position different from the first position; and

a linking unit, wherein:

the actuator is installed below the supporting plane in a vertical direction,

the linking unit is configured to link the mold with the actuator to provide said movement,

the linking unit is connectable to a side surface of the mold, and

in a state where the linking unit is connected to the side surface of the mold with the mold arranged at the second position, at least a part of the actuator is closer to the injection molding machine than the side surface of the mold in a conveying direction of the mold between the first and second positions.

2. The conveyance apparatus according to claim 1 , wherein the linking unit includes at least one linking member configured to transmit a driving force of the actuator to the mold.

3. The conveyance apparatus according to claim 2 , wherein the at least one linking member is configured to move in a direction orthogonal to the conveying direction based on vibrations during said movement of the mold.

4. The conveyance apparatus according to claim 1 , wherein:

the linking unit includes a first linking member and a second linking member,

the first linking member is configured to rotate based on a driving force of the actuator, and

the second linking member is connected to the first linking member and is configured to rotate based on rotation of the first linking member.

5. The conveyance apparatus according to claim 1 , wherein:

the linking unit includes a first linking member and a second linking member,

the first linking member includes a slotted hole and is configured to rotate based on a driving force of the actuator and the second linking member includes a protruding portion that engages with the slotted hole, and

the protruding portion is configured to slide along the slotted hole while the driving force is transmitted from the first linking member to the second linking member.

6. The conveyance apparatus according to claim 1 , wherein:

the linking unit includes a first linking member and a second linking member, and

the first linking member moves along the conveying direction of the mold based on a driving force of the actuator received via the second linking member.

7. The conveyance apparatus according to claim 1 , wherein the actuator includes a cylinder, and at least one linking member of the linking unit is configured to rotate based on an expansion of the cylinder such that the mold moves from the second position to the first position.

8. The conveyance apparatus according to claim 1 . wherein the actuator includes a cylinder, and at least one linking member of the linking unit is configured to rotate based on a contraction of the cylinder such that the mold moves from the second position to the first position.

9. A conveyance apparatus for conveying a mold into an injection molding machine, the conveyance apparatus comprising:

a frame forming a supporting plane for supporting the mold;

an actuator configured to move the mold along the supporting plane; and

a linking unit, wherein:

the actuator is installed below the supporting plane in a vertical direction,

the linking unit is configured to link the mold with the actuator to provide said movement,

the linking unit is connectable to a side surface of the mold, and

the linking unit includes a first linking member configured to rotate by a driving force of the actuator, and a second linking member that is connected to the first linking member and configured to rotate with rotation of the first linking member.

10. A conveyance apparatus for conveying a mold into an injection molding machine, the conveyance apparatus comprising:

a frame forming a supporting plane for supporting the mold;

an actuator configured to move the mold along the supporting plane; and

a linking unit, wherein:

the actuator is installed below the supporting plane in a vertical direction,

the linking unit is configured to link the mold with the actuator to provide said movement,

the linking unit is connectable to a side surface of the mold,

the linking unit includes a first linking member in which a slotted hole is formed and configured to rotate by a driving force of the actuator, and a second linking member that includes a protruding portion that engages with the slotted hole, and

the protruding portion is configured to slide along the slotted hole while the driving force is transmitted from the first linking member to the second linking member.

11. An injection molding system comprising:

an injection molding apparatus configured to perform injection molding with a mold; and

a conveying apparatus configured to convey the mold,

wherein the conveying apparatus comprises:

a frame forming a supporting plane for supporting the mold;

an actuator configured to move the mold along the supporting plane between a first position inside the injection molding machine and a second position different from the first position; and

a linking unit, wherein:

the actuator is installed below the supporting plane in a vertical direction,

the linking unit is configured to link the mold with the actuator to provide said movement,

the linking unit is connectable to a side surface of the mold, and

in a state where the linking unit is connected to the side surface of the mold with the mold arranged at the second position, at least a part of the actuator is closer to the injection molding machine than the side surface of the mold in a conveying direction of the mold between the first and second positions.

12. The injection molding system according to claim 11 , wherein the linking unit includes at least one linking member configured to transmit a driving force of the actuator to the mold.

13. The injection molding system according to claim 12 , wherein the at least one linking member is configured to move in a direction orthogonal to the conveying direction based on vibrations during said movement of the mold.

14. The injection molding system according to claim 11 , wherein:

the linking unit includes a first linking member and a second linking member,

the first linking member is configured to rotate based on a driving force of the actuator, and

the second linking member is connected to the first linking member and is configured to rotate based on rotation of the first linking member.

15. The injection molding system according to claim 11 , wherein:

the linking unit includes a first linking member and a second linking member,

the first linking member includes a slotted hole and is configured to rotate based on a driving force of the actuator and the second linking member includes a protruding portion that engages with the slotted hole, and

the protruding portion is configured to slide along the slotted hole while the driving force is transmitted from the first linking member to the second linking member.

16. A manufacturing method for manufacturing a molded part using the injection molding system according to claim 11 , the method comprising:

moving the mold from the second position to the first position, and injecting a resin to the mold at the first position, wherein, in a state where the mold is at the first position, the mold is closer to the injection molding machine than the actuator in the conveying direction.
